KGRec: A knowledge graph attention-based model for recommender system
Trinh Duong Hoan, Bui Thanh Hung
TL;DR
KGRec is a new recommendation model that uses knowledge graphs and attention mechanisms to improve accuracy and diversity in personalized suggestions.
Contribution
KGRec introduces a novel attention-based knowledge graph model for recommendations that captures higher-order relationships and improves performance.
Findings
KGRec outperforms baseline methods on four benchmark datasets.
The model improves recommendation quality by capturing indirect user-item connections.
KGRec shows robustness and effectiveness in semantic representation learning.
Abstract
Recommender systems have recently gained significant traction as powerful tools for personalized content delivery. While accuracy remains a key focus, users now expect more than precise suggestions. To meet diverse preferences, these systems must also ensure recommendation diversity. They are widely applied in domains such as e-commerce, social media, and online entertainment platforms. Conventional approaches like collaborative filtering mainly emphasize user–item interactions, often overlooking contextual and attribute information, which results in limited performance, especially under sparse data conditions. To address this, we present the KGRec- Knowledge Graph Attention Network Recommendation model, the novel KGRec model integrates knowledge graphs to capture higher-order relationships among users, items, and their associated attributes. KGRec applies multi-layer embedding…
